To promote sustainability and reduce the ecological footprint of recycling processes, this study develops an analytical tool for fast accurate identification components in photovoltaic panels (PVs) Li-Ion battery waste, optimizing material recovery minimizing resource wastage. The laser-induced breakdown spectroscopy (LIBS) technique was selected employed to identify fluoropolymers back sheets determine thickness layers containing fluorine. LIBS also used batteries reveal elemental composition anode, cathode, separator materials. analysis not only revealed all elements contained electrodes but also, case cathode materials, allowed distinguishing a single-component (cathode A LiCoO2) from multi-component materials B mixture LiMn2O4 LiNi0.5Mn1.5O4). results were verified using SEM-EDS XRD examination. Additionally, indirect method identifying (polytetrafluoroethylene (PTFE) or poly(vinylidene fluoride) (PVDF)) prepare dispersions proposed according differences wettability both polymers. By enabling efficient separation, advances sustainable practices, supporting circular economy goals renewable energy sector.
